Typically, automotive interior materials, including car parts, incorporate inorganic substances like glass fibers, whiskers, talc, and calcium carbonate as reinforcing fillers. However, these inorganic materials pose environmental pollution during manufacturing, and parts made using them are difficult to recycle and have poor workability and cost-effectiveness. Conventionally, these inorganic materials are added as fillers to prevent elasticity reduction. However, high-density inorganic reinforcing agents with a specific gravity of 2.5 to 4.0 increase the weight of automotive molded products, consequently increasing the overall weight of vehicles. To address this weight issue, natural fibers meeting the specifications for automotive interiors have been applied to achieve lightweight.

Reducing carbon emissions in compliance with global greenhouse gas reduction policies is a mandatory requirement for global finished vehicle OEMs, and the foremost step in achieving this is the lightweight of vehicles. This technology and product involve producing interior materials using natural fibers aimed at lightweight, including the molding device and method and the product itself. As a primary supplier for global finished vehicle OEMs, Seoyon E-Hwa is proactively developing new technologies and products, focusing on developing lightweight interior parts to meet the demands of its clients and global issues on carbon emission reduction.
